In a video promoting its March for Marriage, the National Organization for Marriage (NOM) incorrectly claims that a majority of Americans oppose gay marriage.

NOM, the nation's most vociferous opponent of marriage equality, is organizing a March 26 rally in Washington to urge the U.S. Supreme Court to uphold the Defense of Marriage Act (DOMA) and Proposition 8, California's 2008 voter-approved constitutional amendment limiting marriage to heterosexual unions.

In a 3-minute video released Thursday, the group also states that it's on “the right side of history,” a mantra used by advocates of equal marriage rights.

“The talking heads on TV will try to make you believe that most Americans are in favor of same-sex marriage and that it's inevitable,” a male narrator states. “The reality is that the majority of Americans want marriage to stay between a man and a woman. When people have the chance to vote on redefining marriage, the overwhelming majority voted to keep it the way it's always been in our country: Between a man and a woman.”

“Will you join us on March 26? Republicans and Democrats and people from all races and creeds will march hand in hand to protect our kids by defending marriage.”

“This is your chance to be on the right side of history. Our freedom depends on it,” the narrator adds. (The video is embedded on this page. Visit our video library for more videos.)

Surveys over the past 18 months have shown a majority of Americans support extending marriage rights to gay couples. During the last election cycle, voters in three states legalized such unions and Minnesotans became the first to reject an amendment seeking to exclude gay couples from marriage.
